[rules-users] Drools Flow :Persistence Problem : Restore StatefulKnowledgeSession from database

Hi, I have a query regarding Drools Persistence. I have a scenario in which I want to know whether drool persistence will work or not. Lets say I am in between a workflow and suddenly my server creashes. Suppose my workFlow was completed upto 3 steps with lets say 2 more steps to go. As I am using drools-persistence Api methods so my data regarding the session , variable and process will go into the database specified by me in the tables 'SessionInfo', VaraibleInstanceInfo', and ProcessInstanceInfo and 'WorkItemInfo' tables of the database. Now as my server crashed and I restarted my application. So now I will restore the session object as my application got crashed from the database using the below code. this.ksession = JPAKnowledgeService.loadStatefulKnowledgeSession(id, kbase , null, env); Now as I have restarted the server, KnowledgeBase object i.e. 'kbase' will become null and so as Environment Class object 'env'. Are KnowledgeBase object are stored as well in the database ??? or I have to create a new KnowledgeBase to load the previous StatefulKnowledgeSession object. So in short how can I restore the previous session or If I cann't restore it can I do that by storing the Knowledgebase object and Environment Object in the database as well. Please help me how can this be achieved. Thanks & Regards Pardeep Ruhil ______________________________________________________________________
